What is Fanuc SP9012 Alarm?

Looking for some better info on this servo fault and some other Fanuc servo alarms.  Any Fanuc technicians have details or a straightforward, simple explanation for the SP9012 alarm?

SSPA:12 OVERCURRENT POWER CIRCUIT

1 Check the motor insulation status.

2 Check the spindle parameters.

3 Replace the Spindle Amplifier.

The motor current is abnormally high. A motor-specific parameter does not match the motor model. Poor motor insulation.

(this is from the Fanuc maintenance manual)
